League titles in the first 20 years of the league (1896-1915):
- 8 Minnesota
- 6 Michigan
- 5 Wisconsin
- 5 Chicago
- 3 Illinois
- 1 Iowa
- 1 Northwestern
- 0 Purdue, Ohio State, Indiana
League titles in the most recent 20 years (2001-2020):
- 11 Ohio State
- 3 Penn State
- 3 Michigan State
- 3 Wisconsin
- 2 Michigan
- 2 Iowa
- 1 Illinois
- 0 Minnesota, Northwestern, Purdue, Indiana, Nebraska, Maryland, Rutgers
The interesting thing about the most recent 20 years is that most of the odd ones were early. Included in the first four of the last 20 years (2001-2004) are:
- Illinois' title
- Both of Iowa's titles
- Both of Michigan's titles
- 1 of Ohio State's 11 titles
In the sixteen seasons since Iowa and Michigan shared the title in 2004 the Buckeyes have 10, PSU, MSU, and UW have three each, and the whole rest of the league (M, MN, IL, IA, NU, PU, IU, UNL, UMD, RU) has none.
